Dental Hygienist Requirements in Utah: Scope of Practice & Direct Access
Dental Hygienists in Utah are regulated by the Utah Dentist and Dental Hygienist Licensing Board. The ADHA records a direct-access provision for Utah — Public Health Dental Hygienist (Sec. 58-69-801) — the rule that decides whether a dental hygienist there can work without a dentist on site; see below for what it covers.

Utah’s Direct-Access Provision: Public Health Dental Hygienist
A dental hygienist may treat patients in specified public health settings pursuant to a written agreement with a dentist.
The settings include a homebound patient's residence, a school, a nursing home, an assisted living facility, a community health center, a federally-qualified health center and a mobile dental health program that employees a dentist.
Provider services: All general supervision preventive functions in scope of practice. Local anesthesia and nitrous oxide administration are not permitted.
Requirements: Must be a licensed Utah dental hygienist and have a written agreement with a collaborating dentist. The agreement provides that the dental hygienist shall refer a patient with a dental need beyond the dental hygienist's scope of practice to a dentist. Each patient must complete an informed consent form that provides that treatment by a dental hygienist is not a substitute for a dental examination by a dentist.
What a Dental Hygienist Can Do in Utah: Permitted Functions & Supervision Levels
Utah lists most dental hygiene functions on the ADHA Practice Act chart at general supervision, where a dentist authorizes the service in advance but need not be present.
Oral prophylaxis, local anesthesia, topical anesthesia, fluoride, pit/fissure sealants, scaling and root planing, soft tissue curettage, study cast impressions, placing and removing periodontal dressings, and removing sutures all sit at that level.
Two functions carry stricter levels: x-rays require direct supervision, meaning the dentist must be present, and administering nitrous oxide requires personal supervision, the chart's strictest tier, where the dentist authorizes the service, is present, and checks the patient before dismissal.
Dental hygiene assessment is listed at direct access.
Dental hygiene diagnosis, treatment planning, prescriptive authority, placing sutures, Botox, lasers, vaccines and dermal fillers are not listed on the chart for Utah.
- X-rays are listed at direct supervision (D) for Utah, meaning the dentist must be present, while most other listed functions sit at general supervision.
- Administering nitrous oxide is listed at personal supervision (P), the strictest level on the chart, requiring the dentist to authorize the service, be present, and check the patient before dismissal.
- Dental hygiene assessment is listed at direct access (A) for Utah, while dental hygiene diagnosis, treatment planning and prescriptive authority all carry no supervision level on the chart.
- Local anesthesia sits at general supervision (G) on the Practice Act chart, the same level as most other listed functions for Utah.
- G
- General supervision: dentist needs to authorize prior to services, but need not be present
- D

- P
- Personal supervision: dentist needs to authorize, be present and check prior to patient dismissal

Local Anesthesia by Dental Hygienists in Utah
Utah's Local Anesthesia chart lists the authority as implemented in 1983 by statute.
It requires direct supervision, meaning the dentist must be present, and covers both block and infiltration injections.
Education must come from an accredited program, and the chart lists the WREB exam as required.
No separate course-hour requirement is listed.
Confirm current permit and continuing-education rules with the Utah Dentist and Dental Hygienist Licensing Board before applying.

Silver Diamine Fluoride by Dental Hygienists in Utah
ADHA's silver diamine fluoride document does not name SDF for Utah.
Instead it quotes a general dental hygiene practice provision, citing §58-69-102, under which ADHA places SDF: dental hygienists may provide dental hygiene care in accordance with a dentist's treatment plan for a patient.
ADHA lists supervision as General for Utah in this document.
The quoted provision does not use the words fluoride or SDF; it conditions hygiene care broadly on the dentist having already set a treatment plan for that patient.
No additional references are listed.
Confirm with the Utah Dentist and Dental Hygienist Licensing Board whether this general authority is understood to cover SDF application.

What Direct Access Does — and Doesn’t — Cover
Direct access is one dimension of scope, not scope itself. The ADHA’s direct-access chart records whether a dental hygienist can initiate treatment and treat a patient without a dentist present — the function-by-function supervision levels and the local anesthesia rules above come from two separate ADHA charts, and the three do not always line up neatly.
Don’t generalize from a direct-access provision to any other part of scope, and confirm specifics with the Utah Dentist and Dental Hygienist Licensing Board.
Frequently Asked Questions
Does a dentist have to supervise a dental hygienist in Utah?
It depends on the setting.
Under the 2015 Public Health Dental Hygienist provision (Sec. 58-69-801), a licensed Utah dental hygienist may treat patients without a dentist present, but only in specified public health settings — a homebound patient's residence, a school, a nursing home, an assisted living facility, a community health center, a federally-qualified health center, or a mobile dental health program that employs a dentist — and only under a written agreement with a collaborating dentist.
That agreement must require referral of patients whose needs exceed the hygienist's scope, and each patient must sign informed consent stating the treatment isn't a substitute for a dental exam.
Local anesthesia and nitrous oxide administration aren't permitted under this provision.
Outside these public health settings, this provision does not apply and is not a blanket unsupervised-practice grant.
Confirm current details with the Utah Dentist and Dental Hygienist Licensing Board.
Who regulates dental hygienists in Utah?
Dental Hygienists in Utah are regulated by the Utah Dentist and Dental Hygienist Licensing Board.
Scope of practice is set by state law and changes over time, so verify current rules directly with the board before relying on them.
Does a Utah dental hygienist need a dentist present to take x-rays?
Yes.
The ADHA Practice Act chart lists X-Rays at direct supervision for Utah, which means the dentist must be present while the hygienist takes them.
That is stricter than most of the other listed functions for Utah, which sit at general supervision, where the dentist authorizes the service in advance but does not have to be in the room.
Confirm current requirements with the Utah Dentist and Dental Hygienist Licensing Board.
What supervision does administering nitrous oxide require in Utah?
The ADHA chart lists administering nitrous oxide at personal supervision for Utah, the strictest level it tracks: the dentist must authorize the service, be present, and check the patient before dismissal.
That is a higher bar than the general supervision level most other listed Utah functions carry.
Verify current rules with the Utah Dentist and Dental Hygienist Licensing Board before relying on this.
Does the Utah chart list dental hygiene diagnosis or prescriptive authority?
No. Dental hygiene diagnosis, treatment planning and prescriptive authority are all marked as not listed on the ADHA Practice Act chart for Utah, which ADHA records as not listed rather than as a ban.
Dental hygiene assessment, by contrast, is listed at direct access.
Contact the Utah Dentist and Dental Hygienist Licensing Board for how Utah law treats each term.
What does the Local Anesthesia chart say about giving injections in Utah?
ADHA's separate Local Anesthesia chart lists Utah's authority as implemented in 1983 by statute, at direct supervision, covering both block and infiltration injections, with education from an accredited program and the WREB exam required; no separate course-hour requirement is listed.
This chart is compiled separately from the Practice Act chart and does not always match its Local Anesthesia cell.
Check with the Utah Dentist and Dental Hygienist Licensing Board for current permit rules.
Does Utah's ADHA entry say a dental hygienist can apply silver diamine fluoride?
The entry does not name SDF for Utah.
It cites §58-69-102 and lists supervision as General, quoting a general provision that a dental hygienist may provide dental hygiene care in accordance with a dentist's treatment plan for a patient.
It is that general authority, not an SDF-specific rule, that ADHA lists here.
Confirm with the Utah Dentist and Dental Hygienist Licensing Board whether it treats SDF as covered under that provision.
